In looking at Job, we see a man's agony and wrestling with the unanswered questions of his suffering. The great lessons contained in this book show many truths about suffering and how to work to resolution of pain to the freedom and restitution God desires.
In the great eighth chapter of Romans, which is the solution to St. Paul's wrestling with his sin in chapter seven, we see a profound truth. It is that those who live according to the flesh and are controlled by its unholy desires, set their minds on and pursue those things which gratify the flesh. But those who are according to the Spirit and are controlled by the desires of the Spirit, set their minds on and seek those things which gratify the Holy Spirit. So the life of the Spirit requires a mind change.
